# RIOT nativenet wireshark dissector
This allows wireshark to parse packets sent over TAP by RIOT's native port.
## Installation
Just copy the script ``riot.lua`` to ``$HOME/.wireshark/plugins`` and restart
Wireshark.
## Usage
### Debian/Ubuntu
Ensure that dumpcat is available for you as non-superusers:
```bash
sudo dpkg-reconfigure wireshark-common
sudo usermod -a -G wireshark $USER
```
### Fedora (and possibly others)
The 'wireshark-devel' package must be installed to run the plugin.
## Configuration
Depending on what you want to send over the native TAP you might want to change
the next header dissector. Currently we have included the dissectors for
IEEE 802.15.4 and 6LoWPAN into the script file, but anything is thinkable.
Refer to the wireshark manual to get the protocol names, e.g.:
```lua
local next_dis = Dissector.get("ipv6")
```
